Indoor and outdoor air pollution and couple fecundability: a systematic review.

BACKGROUND: Air pollution is both a sensory blight and a threat to human health. Inhaled environmental pollutants can be naturally occurring or human-made, and include traffic-related air pollution (TRAP), ozone, particulate matter (PM) and volatile organic compounds, among other substances, including those from secondhand smoking. Studies of air pollution on reproductive and endocrine systems have reported associations of TRAP, secondhand smoke (SHS), organic solvents and biomass fueled-cooking with adverse birth outcomes. While some evidence suggests that air pollution contributes to infertility, the extant literature is mixed, and varying effects of pollutants have been reported. OBJECTIVE AND RATIONALE: Although some reviews have studied the association between common outdoor air pollutants and time to pregnancy (TTP), there are no comprehensive reviews that also include exposure to indoor inhaled pollutants, such as airborne occupational toxicants and SHS. The current systematic review summarizes the strength of evidence for associations of outdoor air pollution, SHS and indoor inhaled air pollution with couple fecundability and identifies gaps and limitations in the literature to inform policy decisions and future research. SEARCH METHODS: We performed an electronic search of six databases for original research articles in English published since 1990 on TTP or fecundability and a number of chemicals in the context of air pollution, inhalation and aerosolization. Standardized forms for screening, data extraction and study quality were developed using DistillerSR software and completed in duplicate. We used the Newcastle-Ottawa Scale to assess risk of bias and devised additional quality metrics based on specific methodological features of both air pollution and fecundability studies. OUTCOMES: The search returned 5200 articles, 4994 of which were excluded at the level of title and abstract screening. After full-text screening, 35 papers remained for data extraction and synthesis. An additional 3 papers were identified independently that fit criteria, and 5 papers involving multiple routes of exposure were removed, yielding 33 articles from 28 studies for analysis. There were 8 papers that examined outdoor air quality, while 6 papers examined SHS exposure and 19 papers examined indoor air quality. The results indicated an association between outdoor air pollution and reduced fecundability, including TRAP and specifically nitrogen oxides and PM with a diameter of ≤2.5 µm, as well as exposure to SHS and formaldehyde. However, exposure windows differed greatly between studies as did the method of exposure assessment. There was little evidence that exposure to volatile solvents is associated with reduced fecundability. WIDER IMPLICATIONS: The evidence suggests that exposure to outdoor air pollutants, SHS and some occupational inhaled pollutants may reduce fecundability. Future studies of SHS should use indoor air monitors and biomarkers to improve exposure assessment. Air monitors that capture real-time exposure can provide valuable insight about the role of indoor air pollution and are helpful in assessing the short-term acute effects of pollutants on TTP.

A Systematic Review of Palliative Care Content in the Doctor of Pharmacy Curriculum.

Objective. To describe the methods of teaching and evaluating palliative care experiences for pharmacy students.Findings. A literature search retrieved 971 reports, from which 26 studies met all of study criteria. Educational interventions concerning palliative care included didactic courses, flipped classrooms, advanced pharmacy practice experiences (APPEs), workshops, and seminars. Total direct hours of education in palliative care ranged from 1-200. Seven (27%) focused experiences were reported as required, while nine (35%) were reported as elective. The majority (n=14, 54%) of studies measured pharmacy students' confidence, attitudes, or perceptions as the main outcome, and of those most studies reported an improvement. Five (19%) studies reported on interprofessional experiences in palliative care conducted in the United States, and four (15%) studies reported on similar experiences conducted outside the United States. When reported, most experiences were developed for students to complete prior to beginning their APPE year. All of the included studies used a non-randomized design.Summary. This review suggests a palliative care experience for pharmacy students should be interprofessional, occur during the year prior to APPEs, and measure skills-based outcomes.

Interventions to Improve Patient Comprehension in Informed Consent for Medical and Surgical Procedures: An Updated Systematic Review.

Background. Patient comprehension is fundamental to valid informed consent. Current practices often result in inadequate patient comprehension. Purpose. An updated review to evaluate the characteristics and outcomes of interventions to improve patient comprehension in clinical informed consent. Data Sources. Systematic searches of MEDLINE and EMBASE (2008-2018). Study Selection. We included randomized and nonrandomized controlled trials evaluating interventions to improve patient comprehension in clinical informed consent. Data Extraction. Reviewers independently abstracted data using a standardized form, comparing all results and resolving disagreements by consensus. Data Synthesis. Fifty-two studies of 60 interventions met inclusion criteria. Compared with standard informed consent, a statistically significant improvement in patient comprehension was seen with 43% (6/14) of written interventions, 56% (15/27) of audiovisual interventions, 67% (2/3) of multicomponent interventions, 85% (11/13) of interactive digital interventions, and 100% (3/3) of verbal discussion with test/feedback or teach-back interventions. Eighty-five percent of studies (44/52) evaluated patients' understanding of risks, 69% (41/52) general knowledge about the procedure, 35% (18/52) understanding of benefits, and 31% (16/52) understanding of alternatives. Participants' education level was reported heterogeneously, and only 8% (4/52) of studies examined effects according to health literacy. Most studies (79%, 41/52) did not specify participants' race/ethnicity. Limitations. Variation in interventions and outcome measures precluded conduct of a meta-analysis or calculation of mean effect size. Control group processes were variable and inconsistently characterized. Nearly half of studies (44%, 23/52) had a high risk of bias for the patient comprehension outcome. Conclusions. Interventions to improve patient comprehension in informed consent are heterogeneous. Interactive interventions, particularly with test/feedback or teach-back components, appear superior. Future research should emphasize all key elements of informed consent and explore effects among vulnerable populations.

Comparing Specialty and Primary Palliative Care Interventions: Analysis of a Systematic Review.

Background: Investigators have tested interventions delivered by specialty palliative care (SPC) clinicians, or by clinicians without palliative care specialization (primary palliative care, PPC). Objective: To compare the characteristics and outcomes of randomized clinical trials (RCTs) of SPC and PPC interventions. Design: Systematic review secondary analysis. Setting/Subjects: RCTs of palliative care interventions. Measurements: Interventions were classified SPC if delivered by palliative care board-certified or subspecialty trained clinicians, or those with extensive clinical experience; all others were PPC. We abstracted data for each intervention: delivery setting, delivery clinicians, outcomes measured, trial results, and Cochrane's Risk of Bias. We conducted narrative synthesis for quality of life, symptom burden, and survival. Results: Of 43 RCTs, 27 tested SPC and 16 tested PPC interventions. SPC interventions were more comprehensive (4.2 elements of palliative care vs. 3.1 in PPC, p = 0.02). SPC interventions were delivered in inpatient (44%) or outpatient settings (52%) by specialty physicians (44%) and nurses (44%); PPC interventions were delivered in inpatient (38%) and home settings (38%) by nurses (75%). PPC trials were more often of high risk of bias than SPC trials. Improvements were demonstrated on quality of life by SPC and PPC trials and on physical symptoms by SPC trials. Conclusions: Compared to PPC, SPC interventions were more comprehensive, were more often delivered in clinical settings, and demonstrated stronger evidence for improving physical symptoms. In the face of SPC workforce limitations, PPC interventions should be tested in more trials with low risk of bias, and may effectively meet some palliative care needs.

Comparison of Palliative Care Interventions for Cancer versus Heart Failure Patients: A Secondary Analysis of a Systematic Review.

Background: In 2016, Kavalieratos and colleagues performed a systematic review of randomized clinical trials (RCTs) of palliative care (PC) interventions. The majority of RCTs included focused on oncology, with fewer in heart failure (HF). Cancer patients' often predictable decline differs from the variable illness trajectories of HF; however, both groups experience similar palliative needs, and accordingly, PC in HF continues to grow. Objective: To investigate if PC interventions differ between cancer and HF patients. Design: In this secondary analysis, we compare PC interventions for cancer and HF patients evaluated in the 2016 systematic review. Settings/Subjects: We included a total of 25 trials, 19 of which included 3730 cancer patients, and 6 of which included 1049 HF patients (mean age, 67 years). Measurements: We compared the following five characteristics among included trials: PC domains addressed, duration, location, provider specialization, and measured outcomes. Results: The content of the cancer and HF interventions was similar. HF interventions tended to include more home-based (50% vs. 37%) and specialty PC interventions (67% vs. 47%), although these results did not reach statistical significance. Both cancer and HF interventions favored longer durations (i.e., more than one month; 79% and 67%). No HF intervention RCTs included caregiver outcomes, whereas 32% of cancer interventions did. Conclusions: There were no substantial differences in content of cancer and HF interventions, although the latter tended to be delivered by PC specialists at home. There is a need for scalable interventions that incorporate the needs and preferences of individual patients, regardless of diagnosis.

The IOU Consensus Recommendations for Empirical Therapy of Cystitis in Nursing Home Residents.

OBJECTIVE: To establish consensus recommendations for empirical treatment of uncomplicated cystitis with anti-infectives in noncatheterized older nursing home residents to be implemented in the Improving Outcomes of UTI Management in Long-Term Care Project (IOU) funded by the Agency for Healthcare Research and Quality. DESIGN: Two-round modified Delphi survey. PARTICIPANTS: Expert panel of 19 clinical pharmacists. MEASUREMENTS: Comprehensive literature search and development/review/edit of draft survey by the investigative group (one geriatric clinical pharmacist, two geriatric medicine physicians, and one infectious disease physician). The expert panel members rated their agreement with each of 31 recommendations for drugs of choice, dosing medications at various levels of renal function, drug-drug interactions to avoid, and duration of therapy by sex on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Consensus agreement was defined as a lower 95% confidence limit of 4.0 or higher for the recommendation-specific mean score. RESULTS: The response rate was 95% for the first round, and three recommendations achieved consensus (dosing for nitrofurantoin and trimethoprim/sulfamethoxazole in those without chronic kidney disease, and drug-drug interaction between trimethoprim/sulfamethoxazole and warfarin). In the second round, 90% responded and reached consensus on an additional eight recommendations (two for nitrofurantoin or trimethoprim/sulfamethoxazole as initial drugs of choice, three for dosing ciprofloxacin, nitrofurantoin, and trimethoprim/sulfamethoxazole at various levels of chronic kidney disease, and three drug-drug interactions to avoid: trimethoprim/sulfamethoxazole with phenytoin and ciprofloxacin with theophylline or with tizanidine). CONCLUSION: An expert panel of clinical pharmacists was able to reach consensus on a set of recommendations for the empirical treatment of cystitis with oral anti-infective medications in older nursing home residents. The recommendations were incorporated into a treatment algorithm for uncomplicated cystitis in noncatheterized nursing home residents and used in educational materials for health professionals in an ongoing controlled intervention study.

Impact of community pharmacist-provided preventive services on clinical, utilization, and economic outcomes: An umbrella review.

Preventable diseases and late diagnosis of disease impose great clinical and economic burden for health care systems, especially in the current juncture of rising medical expenditures. Under these circumstances, community pharmacies have been identified as accessible venues to receive preventive services. This umbrella review aims to examine existing evidence on the impact of community pharmacist-provided preventive services on clinical, utilization, and economic outcomes in the United States (US). We included systematic reviews, narrative reviews and meta-analyses published in English between January 2007 and October 2017. Of 2742 references identified by our search strategy, a total of 13 research syntheses met our inclusion criteria. Included reviews showed that community pharmacists are effective at increasing immunization rates, supporting smoking cessation, managing hormonal contraception therapies, and identifying patients at high risk for certain diseases. Moreover, evidence suggests that community pharmacies are especially well-positioned for the provision of preventive services due to their convenient location and extended hours of operation. There is general agreement on the positive impact of community pharmacists in increasing access to preventive health, particularly among patients who otherwise would not be reached by other healthcare providers. The provision of preventive services at US community pharmacies is feasible and effective, and has potential for improving patient outcomes and health system efficiency. However, high-quality evidence is still lacking. As the healthcare landscape shifts towards a value-based framework, it will be important to conduct robust studies that further evaluate the impact of community pharmacist-provided preventive services on utilization and economic outcomes.

The Improving Outcomes of UTI Management in Long-Term Care Project (IOU) Consensus Guidelines for the Diagnosis of Uncomplicated Cystitis in Nursing Home Residents.

OBJECTIVES: To identify a set of signs and symptoms most likely to indicate uncomplicated cystitis in noncatheterized nursing home residents ≥65 years of age using consensus-based methods informed by a literature review. DESIGN: Literature review and modified Delphi survey with strict inclusion criteria. SETTING AND PARTICIPANTS: Expert panel of 20 physicians certified in geriatric medicine and/or medical direction, actively practicing in post-acute and long-term care settings. METHODS: The authors performed a literature review to produce a comprehensive list of potential signs and symptoms of presumptive uncomplicated cystitis, including nonspecific "quality control" items deemed unlikely to indicate uncomplicated cystitis. The expert panel rated their agreement for each sign/symptom using a 5-point Likert-type scale (1 = strongly disagree to 5 = strongly agree). Agreed upon signs and symptoms were summarized using a diagnostic algorithm for easy clinical use. RESULTS: The literature review identified 16 signs and symptoms that were evaluated in 3 Delphi survey rounds. The response rate was 100% for round 1 and 95% for the second 2 rounds. Consensus agreement for inclusion was achieved for dysuria on round 1 with exclusion of the 3 quality controls, and "offensive smelling urine." Consensus in the second round was reached for including 4 additional items (gross hematuria, suprapubic pain, urinary frequency, and urinary urgency). Round 3 evaluated dysuria alone and combinations of symptoms. Consensus that dysuria alone is sufficient for diagnosis of cystitis was not reached. CONCLUSIONS/IMPLICATIONS: The panel identified 5 signs and symptoms likely indicative of uncomplicated cystitis in nursing home residents and developed a diagnostic algorithm that can be used to promote antibiotic stewardship in nursing homes. Given similarities in populations, the algorithm may also be applicable to the older adult and the broader post-acute/long-term care populations.

Association Between Palliative Care and Patient and Caregiver Outcomes: A Systematic Review and Meta-analysis.

Importance: The use of palliative care programs and the number of trials assessing their effectiveness have increased. Objective: To determine the association of palliative care with quality of life (QOL), symptom burden, survival, and other outcomes for people with life-limiting illness and for their caregivers. Data Sources: MEDLINE, EMBASE, CINAHL, and Cochrane CENTRAL to July 2016. Study Selection: Randomized clinical trials of palliative care interventions in adults with life-limiting illness. Data Extraction and Synthesis: Two reviewers independently extracted data. Narrative synthesis was conducted for all trials. Quality of life, symptom burden, and survival were analyzed using random-effects meta-analysis, with estimates of QOL translated to units of the Functional Assessment of Chronic Illness Therapy-palliative care scale (FACIT-Pal) instrument (range, 0-184 [worst-best]; minimal clinically important difference [MCID], 9 points); and symptom burden translated to the Edmonton Symptom Assessment Scale (ESAS) (range, 0-90 [best-worst]; MCID, 5.7 points). Main Outcomes and Measures: Quality of life, symptom burden, survival, mood, advance care planning, site of death, health care satisfaction, resource utilization, and health care expenditures. Results: Forty-three RCTs provided data on 12 731 patients (mean age, 67 years) and 2479 caregivers. Thirty-five trials used usual care as the control, and 14 took place in the ambulatory setting. In the meta-analysis, palliative care was associated with statistically and clinically significant improvements in patient QOL at the 1- to 3-month follow-up (standardized mean difference, 0.46; 95% CI, 0.08 to 0.83; FACIT-Pal mean difference, 11.36] and symptom burden at the 1- to 3-month follow-up (standardized mean difference, -0.66; 95% CI, -1.25 to -0.07; ESAS mean difference, -10.30). When analyses were limited to trials at low risk of bias (n = 5), the association between palliative care and QOL was attenuated but remained statistically significant (standardized mean difference, 0.20; 95% CI, 0.06 to 0.34; FACIT-Pal mean difference, 4.94), whereas the association with symptom burden was not statistically significant (standardized mean difference, -0.21; 95% CI, -0.42 to 0.00; ESAS mean difference, -3.28). There was no association between palliative care and survival (hazard ratio, 0.90; 95% CI, 0.69 to 1.17). Palliative care was associated consistently with improvements in advance care planning, patient and caregiver satisfaction, and lower health care utilization. Evidence of associations with other outcomes was mixed. Conclusions and Relevance: In this meta-analysis, palliative care interventions were associated with improvements in patient QOL and symptom burden. Findings for caregiver outcomes were inconsistent. However, many associations were no longer significant when limited to trials at low risk of bias, and there was no significant association between palliative care and survival.

Review of hookah tobacco smoking among college students: policy implications and research recommendations.

BACKGROUND: About 30% of college students have smoked hookah tobacco. Although most students perceive this product to be innocuous and non-addictive, hookah tobacco increases the risk for disease and nicotine dependence. Currently, the US Food and Drug Administration (FDA) does not regulate the manufacture, distribution, or sale of hookah tobacco. OBJECTIVE: Empirical literature pertaining to hookah tobacco smoking is reviewed with a focus on the implications for regulatory policy. METHODS: PubMed, PsycINFO, and Scopus databases were searched to locate articles published in English. The literature search combined several key words including "hookahs", "college", "advertising", "health effects", and "health policy". RESULTS: Smoking hookah tobacco may play a role in the initiation of smoking among tobacco-naïve college students and may portend persistent smoking among those who have smoked cigarettes. College students are typically nondaily, social smokers. They do not perceive that their heightened risk for tobacco diseases and nicotine dependence relates to their smoking behavior. However, few public health messages target college-age adults to counter media messages that endorse hookah tobacco smoking. CONCLUSION: Given that the FDA is not authorized to ban specific tobacco products, policy actions should focus on the development of effective risk communication strategies that target college-age adults and on limiting the accessibility of hookah tobacco products to these adults. Accordingly, a research agenda that would inform these policy actions is proposed.
