Identifying reasons for delays in acute hospitals using the Day-of-Care Survey method.

This paper describes a new tool called 'Day-of-Care Survey', developed to assess inpatient delays in acute hospitals. Using literature review, iterative testing and feedback from professional groups, a national multidisciplinary team developed the survey criteria and methodology. Review teams working in pairs visited wards and used case records and bedside charts to assess the patient's status against severity of illness and service intensity criteria. Patients who did not meet the survey criteria for acute care were identified and delays were categorised. From March 2012 to December 2013, nine acute hospitals across Scotland, Australia and England were surveyed. A total of 3,846 adult general inpatient beds (excluding intensive care and maternity) were reviewed. There were 145 empty beds at the time of surveys across the nine sites, with 270 definite discharges planned on the day of the survey. The total number of patients not meeting criteria for acute care was 798/3,431 (23%, range 18-28%). Six factors accounted for 61% (490/798) of the reasons why patients not meeting acute care criteria remained in hospital. This survey gives important insights into the challenges of managing inpatient flow using system level information as a method to target interventions designed to address delay.

A prospective audit of bed utilisation and delays in care across London.

BACKGROUND: A prospective bed utilisation census of acute London hospitals using an established Day of Care Survey (DoCS), which quantified adult patients not meeting criteria for in-hospital care. METHODS: Twenty-three hospitals were surveyed over two weeks in October/November 2017 using supervised trained hospital staff. Pairs of staff visited wards, reviewed all patients and identified those not meeting inpatient care criteria, recording reasons for delay. Patient demographics, length of stay (LOS), ward specialty and delay reasons were collected. RESULTS: Overall - In total, 8,656 in-patients were studied (overall occupancy 96%, range 82-117%): 800 definite discharges were excluded, leaving 7,856 patients for analysis; seven hospitals had °100% occupancy; 1,919/7,856 patients (24%, range 12-43%) did not meet criteria; 56% of patients were over 70 years; five hospitals had higher number of patients <70yo 56% patients had LOS 0˛7days. Delayed patients - Number of delayed patients increased with age, but three hospitals had more patients <70yo; 53% had LOS˛14 days and 47% LOS<14 days; 13 hospitals had greater/equal number of patients in ˛14 days LOS. For delayed patients in ˛14 days group, most were within seven days of admission (627 ˛7days, 393 8-14 days). In total 34% (range 11-54%) of delays were related to acute hospital reasons (AHR) and 61% (range 46-83%) to wider system reasons (WSR). Eight common themes accounted for 67% of recorded reasons and were equally split between AHR and WSR. CONCLUSION: Data showed high occupancy levels with insufficient discharges. This study suggests policies selecting age and/or LOS alone as cut offs to tackle delays in care may miss a large proportion of patients requiring more timely interventions. Adopting a proactive thematic approach to improvement using the top eight delay reasons provides an obvious opportunity to reduce delays while noting the inter site variation. All metrics analysed emphasized the need for informed local data to help support local change.

Nanoscale imaging of clinical specimens using conventional and rapid-expansion pathology.

In pathology, microscopy is an important tool for the analysis of human tissues, both for the scientific study of disease states and for diagnosis. However, the microscopes commonly used in pathology are limited in resolution by diffraction. Recently, we discovered that it was possible, through a chemical process, to isotropically expand preserved cells and tissues by 4-5× in linear dimension. We call this process expansion microscopy (ExM). ExM enables nanoscale resolution imaging on conventional microscopes. Here we describe protocols for the simple and effective physical expansion of a variety of human tissues and clinical specimens, including paraffin-embedded, fresh frozen and chemically stained human tissues. These protocols require only inexpensive, commercially available reagents and hardware commonly found in a routine pathology laboratory. Our protocols are written for researchers and pathologists experienced in conventional fluorescence microscopy. The conventional protocol, expansion pathology, can be completed in ~1 d with immunostained tissue sections and 2 d with unstained specimens. We also include a new, fast variant, rapid expansion pathology, that can be performed on <5-µm-thick tissue sections, taking <4 h with immunostained tissue sections and <8 h with unstained specimens.

Non-tuberculous mycobacteria masquerading as aspiration pneumonia in patients with gastrointestinal problems.

The association between non-tuberculous mycobacterial pulmonary disease and achalasia, although previously documented in the respiratory literature, is not well recognised generally. We present a case of a female who presents with weight loss, cough and radiological findings of aspiration pneumonia and achalasia. A discussion of mechanisms for this association are presented.

A longitudinal study of lung function in nonsmoking patients with rheumatoid arthritis.

STUDY OBJECTIVE: s: Patients with rheumatoid arthritis (RA) have a high prevalence of pulmonary function test (PFT) abnormality, but the long-term significance of this is unknown. We performed a longitudinal study of pulmonary function in asymptomatic, nonsmoking patients with active RA requiring disease-modifying drugs. We looked for temporal change in lung function and characteristics that would predict subsequent development of PFT abnormality or respiratory symptoms. METHODS: In 1990, 52 patients (44 women; age range, 29 to 78 years; median, 56 years) underwent clinical assessment (drug history, RA severity, immunologic, and inflammatory markers) and PFTs (spirometry, body plethysmography, gas transfer). PFT results were expressed as standardized residuals (SRs). Thirty-eight patients were reassessed in 2000. A self-administered questionnaire was used to identify respiratory symptoms. RESULTS: The prevalence of pulmonary function abnormality was higher than expected compared with a reference population, but there was no significant increase in number over 10 years (8.7% in 1990 and 8.8% in 2000). When assessed by group means and compared with reference values, reduced diffusing capacity of the lung for carbon monoxide (DLCO) and increased ratio of residual volume (RV) to total lung capacity (TLC) [RV/TLC] were the only abnormalities to develop over the study period (mean DLCO in 2000, - 0.47 SR; 95% confidence interval [CI], - 0.91 to - 0.01; RV/TLC, 0.49 SR; 95% CI, 0.13 to 0.84). However, rates of change of pulmonary function variables were not significantly different from zero. Logistic regression did not identify any meaningful relationship between disease characteristics and PFT abnormality. CONCLUSIONS: Asymptomatic patients with RA have a higher prevalence of PFT abnormality than expected, but these do not increase in number over time. We did not identify any patient or disease-specific characteristic that could predict the development of respiratory disease in patients with RA. Analysis using percentage of predicted values, rather than SRs, is misleading as it exaggerates the extent of abnormality present. Abnormal lung function is a common and probably benign finding in nonsmoking, asymptomatic patients with RA.

The proportion of general practitioner referrals to a hospital Respiratory Medicine clinic suitable to be seen in a GPwSI Respiratory Clinic.

AIMS: The purpose of this study was to examine the proportion of general practitioner (GP) referrals to a hospital Respiratory Medicine clinic which might be suitable for a General Practitioner with a Special Interest (GPwSI) Respiratory Clinic. METHOD: All GP referral letters to the Respiratory Medicine Department of a teaching hospital, apart from urgent cancer referrals, were identified from two two-week periods. All patient and practice identifications were removed. Two GPs and one Consultant Respiratory Physician assessed each of the anonymised referral letters to determine the patient's suitability to be seen in a GPwSI Respiratory Clinic, assuming such a clinic had a predetermined range of investigative facilities. RESULTS: Out of 96 referrals covering a wide range of respiratory conditions apart from lung cancer, 22 (23%) were considered by all assessors to be suitable for a GPwSI clinic, and there was full agreement that 40 referrals (42%) were unsuitable. The other 34 referrals (35%) had varying degrees of agreement on suitability. The largest groups of patient referrals considered suitable for a GPwSI clinic were those with chronic obstructive pulmonary disease (COPD) or cough as the main presenting clinical problem. The commonest groups considered unsuitable were referrals of patients with an abnormal chest radiograph, haemoptysis, or possible interstitial lung disease. CONCLUSION: This small study has shown that at least a fifth of GP referrals to a hospital Respiratory Medicine clinic could be seen in a suitably resourced GPwSI clinic, with consequent reductions in hospital outpatient waiting lists and improved accessibility for patients. This finding will be of interest to potential commissioners of GPwSI services especially with the advent of Practice-based Commissioning.

Cholelithoptysis: an unusual delayed complication of laparoscopic cholecystectomy.

We report the case of a 54-year old woman who presented with a persistent right lower lobe pneumonia followed by cholelithoptysis, 11 months after a laparoscopic cholecystectomy. It is postulated that this was a result of the formation of a subphrenic abscess secondary to intraoperative spillage of gallstones. It is concluded that spillage of gallstones at laparoscopic cholecystectomy is not as benign as previously thought and that efforts to prevent spillage should include scrupulous operative technique, especially in the presence of gallbladder inflammation, and especial care when removing the gallbladder from the abdominal cavity.
