RESUMEN
OBJECTIVES: To compare the outcomes and safety of a rapid access chest pain clinic (RACPC) in Australia with those of a general cardiology clinic. DESIGN: Prospective comparison of the outcomes for patients attending an RACPC and those of historical controls. SETTING: Royal Hobart Hospital cardiology outpatient department. PARTICIPANTS: 1914 patients referred for outpatient evaluation of new onset chest pain (1479 patients seen in the RACPC, 435 patients previously seen in the general cardiology clinic). MAIN OUTCOME MEASURES: Service outcomes (review times, number of clinic reviews); adverse events (unplanned emergency department re-attendances at 30 days and 12 months; major adverse cardiovascular events at 12 months, including unplanned revascularisation, acute coronary syndrome, stroke, cardiac death). RESULTS: Median time to review was shorter for RACPC than for usual care patients (12 days [IQR, 8-15 days] v 45 days [IQR, 27-89 days]). All patients seen in the RACPC received a diagnosis at the first clinic visit, but only 139 patients in the usual care group (32.0%). There were fewer unplanned emergency department re-attendances for patients in the RACPC group at 30 days (1.6% v 4.4%) and 12 months (5.7% v 12.9%) than in the control group. Major adverse cardiovascular events were less frequent among patients evaluated in the RACPC (0.2% v 1.4%). CONCLUSIONS: Patients were evaluated more efficiently in the RACPC than in a traditional cardiology clinic, and their subsequent rates of emergency department re-attendances and adverse cardiovascular events were lower.

OBJECTIVE: This study aimed to determine what effect environmental noise has upon the psychological and physiological stress response of medical students during simulated laparoscopic surgery. MATERIALS AND METHODS: An anonymous cohort of medical students were randomized into 2 arms and performed a laparoscopic task on a simulator. The "control" group performed the task in silence, whereas the "noise" group were exposed to an 80 dB verbal recording. Operator stress response was measured using a validated acute stress questionnaire and continuous heart rate (HR). RESULTS: A total of 70 medical students participated. The "state" component of the State Trait Anxiety Inventory questionnaire increased significantly following the task in both groups with globally higher scores recorded in the noise group. Peak-resting HR values were significantly higher in the noise group. Mean-resting HR was significantly higher in the noise group. CONCLUSIONS: Environmental noise in a simulated theater environment generates a measurable increase in operator stress response during laparoscopy.

BACKGROUND: The global burden of surgical disease has not been well quantified, but is potentially immense. Given the enormity of the problem and the relative paucity of data, definition and monitoring of surgical burden of disease is an essential step in confronting the problem. This study aimed to estimate the prevalence of non-acute surgical disease symptoms in a low-income population. METHODS: The survey was conducted as part of the Indus Hospital Community Cohort in Karachi, Pakistan. A systematic random sampling design was used to enroll 667 households from March to August 2011. An unvalidated questionnaire intending to measure prevalence of surgical symptoms was administered to 780 participants. RESULTS: 761 participants completed the screening questionnaire, with 346 (45%) reporting one or more symptoms requiring surgical assessment (excluding those screened positive for symptoms of osteoarthritis), of which only 8.4% followed up on scheduled appointments at the referral hospital. A total of 126 past surgical procedures were recorded in 120 participants. CONCLUSION: There is a high prevalence of symptoms suggestive of surgical diseases in our urban catchment population with relatively convenient access to health facilities including a tertiary care hospital providing free of cost care. The perceived severity of symptoms, and a complex interaction of other factors, may play an important role in understanding health seeking behavior in our population. Developing a context-specific validated tool to correctly identify surgical symptoms disease in the community with appropriate referral for early management is essential to identify and therefore reduce the burden of surgical diseases within the community. This must happen hand in hand with further studies to understand the barriers to seeking timely health care.

In Pakistan, despite publically available free testing and treatment throughout the country, there were an estimated 58,000 deaths due to tuberculosis in 2010. Understanding the experiences of people affected by TB is essential in addressing barriers to effective treatment. The Indus Hospital used Photovoice to understand the experiences of people affected by TB in Karachi. Two hundred and thirty photographs and stories were collected from 55 people affected by TB. Five major themes and 12 sub-themes emerged from the data: the physical aspects of TB (weakness and the side effects of the medication), the social aspects of TB (loneliness, stigma, and the fear/guilt of infecting family members), the socio-economic aspects of TB (financial difficulties/poverty and poor living conditions), supportive factors during treatment (support from family and friends, support from welfare organizations, prayer, visiting peaceful places), and recovery (happiness about getting better). The photographs, stories, and a Call for Action were shared at a Gallery event with patients, practitioners, and policy-makers. This study provides a look at the complexities surrounding TB and emphasizes the need for holistic interventions for TB that address all aspects of the disease, including its social determinants. It also highlights the potential of Photovoice as an effective means to bring much-needed attention to this disease.

BACKGROUND: Chronic kidney disease (CKD) is being increasingly recognized as a leading public health problem. However, there are limited data available with respect to prevalence of CKD in Pakistan, a developing South Asian country. The study presents the baseline findings of prevalence and risk factors for adult kidney disease in a Pakistani community cohort. METHODS: A total of 667 households were enrolled between March 2010 and August 2011 including 461 adults, aged 15 and older. Mild kidney disease was defined as estimated Glomerular Filtration Rate (eGFR) ≥60 ml/min with microalbuminuria ≥ 30 mg/dl and moderate kidney disease was defined as eGFR <60 ml/min (with or without microalbuminuria). RESULTS: The overall prevalence of kidney disease was 16.6% with 8.6% participants having mild kidney disease and 8% having moderate kidney disease. Age was significantly associated with kidney disease (p < 0.0001). The frequency of diabetes, hypertension and smoking differed significantly among the three groups, i.e., no kidney disease, mild kidney disease and moderate kidney disease. CONCLUSION: Our study results suggest that the burden of kidney disease in this population is found considerable and comparable to neighboring developing countries. We believe that these results have critical implications on health and economics of these countries and due to the epidemic of diabetes, hypertension, cardiovascular disease, smoking and association with worsening poverty, further rapid growth is expected. There is an urgent need for early recognition and prevention strategies based on risk factors and disease trends determined through longitudinal research.

BACKGROUND: The demographic transition in South Asia coupled with unplanned urbanization and lifestyle changes are increasing the burden of non-communicable disease (NCD) where infectious diseases are still highly prevalent. The true magnitude and impact of this double burden of disease, although predicted to be immense, is largely unknown due to the absence of recent, population-based longitudinal data. The present study was designed as a unique 'Framingham-like' Pakistan cohort with the objective of measuring the prevalence and risk factors for hypertension, obesity, diabetes, coronary artery disease and hepatitis B and C infection in a multi-ethnic, middle to low income population of Karachi, Pakistan. METHODS: We selected two administrative areas from a private charitable hospital's catchment population for enrolment of a random selection of cohort households in Karachi, Pakistan. A baseline survey measured the prevalence and risk factors for hypertension, obesity, diabetes, coronary artery disease and hepatitis B and C infection. RESULTS: Six hundred and sixty-seven households were enrolled between March 2010 and August 2011. A majority of households lived in permanent structures (85%) with access to basic utilities (77%) and sanitation facilities (98%) but limited access to clean drinking water (68%). Households had high ownership of communication technologies in the form of cable television (69%) and mobile phones (83%). Risk factors for NCD, such as tobacco use (45%), overweight (20%), abdominal obesity (53%), hypertension (18%), diabetes (8%) and pre-diabetes (40%) were high. At the same time, infectious diseases such as hepatitis B (24%) and hepatitis C (8%) were prevalent in this population. CONCLUSION: Our findings highlight the need to monitor risk factors and disease trends through longitudinal research in high-burden transition communities in the context of rapid urbanization and changing lifestyles. They also demonstrate the urgency of public health intervention programs tailored for these transition communities.

BACKGROUND: In many countries with a high burden of tuberculosis, most patients receive treatment in the private sector. We evaluated a multifaceted case-detection strategy in Karachi, Pakistan, targeting the private sector. METHODS: A year-long communications campaign advised people with 2 weeks or more of productive cough to seek care at one of 54 private family medical clinics or a private hospital that was also a national tuberculosis programme (NTP) reporting centre. Community laypeople participated as screeners, using an interactive algorithm on mobile phones to assess patients and visitors in family-clinic waiting areas and the hospital's outpatient department. Screeners received cash incentives for case detection. Patients with suspected tuberculosis also came directly to the hospital's tuberculosis clinic (self-referrals) or were referred there (referrals). The primary outcome was the change (from 2010 to 2011) in tuberculosis notifications to the NTP in the intervention area compared with that in an adjacent control area. FINDINGS: Screeners assessed 388,196 individuals at family clinics and 81,700 at Indus Hospital's outpatient department from January-December, 2011. A total of 2416 tuberculosis cases were detected and notified via the NTP reporting centre at Indus Hospital: 603 through family clinics, 273 through the outpatient department, 1020 from self-referrals, and 520 from referrals. In the intervention area overall, tuberculosis case notification to the NTP increased two times (from 1569 to 3140 cases) from 2010 to 2011--a 2·21 times increase (95% CI 1·93-2·53) relative to the change in number of case notifications in the control area. From 2010 to 2011, pulmonary tuberculosis notifications at Indus Hospital increased by 3·77 times for adults and 7·32 times for children. INTERPRETATION: Novel approaches to tuberculosis case-finding involving the private sector and using laypeople, mobile phone software and incentives, and communication campaigns can substantially increase case notification in dense urban settings.
