WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT • Potentially inappropriate prescribing in older people is a well‐documented problem and has been associated with adverse drug reactions and hospitalization.• Beers' criteria, Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) and Screening Tool to Alert doctors to Right Treatment (START) are screening tools that have been formulated to help physicians and pharmacists identify potentially inappropriate prescribing and potential prescribing omissions.• The prevalence of potentially inappropriate prescribing and prescribing omissions in the elderly population presenting to hospital with acute illness is high according to STOPP and START criteria. WHAT THIS STUDY ADDS • Potential errors of prescribing and of omission of medicines are prevalent among medically stable older people in primary care.• Screening tools should be incorporated into the everyday practice of primary care doctors and community pharmacists as a means of preventing potential errors of prescribing commission and prescribing omission in older people.AIMS Screening tools have been formulated to identify potentially inappropriate prescribing (IP) in older people. Beers' criteria are the most widely used but have disadvantages when used in Europe. New IP screening tools called Screening Tool of Older Person's Prescriptions (STOPP) and Screening Tool to Alert doctors to Right Treatment (START) have been developed to identify potential IP and potential prescribing omissions (PPOs). The aim was to measure the prevalence rates of potential IP and PPOs in primary care using Beers' criteria, STOPP and START.METHODS Case records of 1329 patients ≥65 years old from three general practices in one region of southern Ireland were studied. The mean age ± SD of the patients was 74.9 ± 6.4 years, 60.9% were female. Patients' current diagnoses and prescription medicines were reviewed and the Beers' criteria, STOPP and START tools applied.RESULTS The total number of medicines prescribed was 6684; median number of medicines per patient was five (range 1–19). Overall, Beers' criteria identified 286 potentially inappropriate prescriptions in 18.3% (243) of patients, whilst the corresponding IP rate identified by STOPP was 21.4% (284), in respect of 346 potentially inappropriate prescriptions. A total of 333 PPOs were identified in 22.7% (302) of patients using the START tool.CONCLUSION Potentially inappropriate drug prescribing and errors of drug omission are highly prevalent among older people living in the community. Prevention strategies should involve primary care doctors and community pharmacists.

We reviewed a single-surgeon series of 300 athletic patients who had undergone reconstruction of the anterior cruciate ligament in order to establish the relationship between the timing of the reconstruction and the incidence of meniscal and chondral pathology. The patients were divided into five groups according to the time from their injury to surgery as follows: less than two months, two to six months, six to 12 months, 12 to 18 months and more than 18 months. The presence of meniscal tears was recorded and chondral pathology was scored according to the system of the French Society of Arthroscopy. There was a significantly higher chance of a medial meniscal tear occurring in patients undergoing reconstruction after one year from their injury (odds ratio (7.99, p = 0.004). The odds of having a lateral meniscal tear did not change significantly with an increasing interval to reconstruction. The chance of patients developing degenerative changes was found to be significantly higher in the groups operated on after six months from injury (odds ratio 4.04, p = 0.005). We advocate that patients with deficiency of the anterior cruciate ligament should be counselled that there is a significant relationship between the duration of the instability of their knee and the subsequent incidence of both chondral changes and meniscal tears. In order to minimise these risks, we recommend that reconstruction be performed within the first year from injury.

Adverse drug events (ADEs) are an important problem in all hospitalized patients as these events represent medication-related patient harm. Few epidemiologic data exist regarding ADEs in the pediatric inpatient setting and, in particular, the economic impact of such ADEs upon the healthcare sector. To evaluate the incidence, preventability, and seriousness of ADEs and potential ADEs occurring in hospitalized children and to examine the cost implications of these ADEs. This was a prospective observational cohort study conducted in the pediatric, neonatal intensive care unit (NICU), and postnatal wards of a university-affiliated urban general hospital in Dunedin, New Zealand (NZ). The study population was all patients admitted to these wards for >24 hours over a 12-week period from 18 March 2002 to 9 June 2002. Medication-related events were identified by chart review, attendance at multidisciplinary clinical meetings, parent/carer/child interviews, and voluntary and verbally solicited reports from staff. All suspected medication-related events were reviewed by a panel of three health professionals who independently categorized the events and rated them for seriousness, preventability, and causality, using a standardized reviewer form. Costs attributable to ADEs were calculated using both the average cost of a bed day, and specific costs for diagnostic groupings. The main outcome measures of the study were ADEs and potential ADEs. There were 495 eligible study patients, who had a total of 520 admissions and 3037 patient-days of admission, during which 3160 prescription episodes were written. There were 67 ADEs, of which 38 (56.7%) were classified as preventable, and 77 potential ADEs. ADEs occurred at a rate of 2.1 per 100 prescription episodes, 12.9 per 100 admissions, and 22.1 per 1000 patient-days. Potential ADEs occurred at a rate of 2.4 per 100 prescription episodes, 14.6 per 100 admissions, and 25 per 1000 patient-days. Although the greatest number (and rate per 100 admissions) of ADEs occurred in NICU patients, surgical pediatric ward patients had the greatest rate of ADEs per 1000 patient-days. Few events occurred in postnatal patients. Forty-six percent of ADEs were classified as being serious; 15% were deemed to result in persistent disability or were classified as life threatening. Potential ADEs were deemed more likely to be serious with 82% classified as potentially serious events; 33% were deemed as having the potential to result in persistent disability, or the potential to cause a life-threatening event. Fifteen ADEs were judged to have caused the hospital admission or to have prolonged hospital stay. The total number of days attributed to ADEs was 92 (range 1-26 days); of these, 58 were deemed preventable days and 34 non-preventable days. This extrapolates to a total annual cost of $NZ235 214 (2002 values) to the pediatric service, subdivided into $NZ148 287 for preventable ADEs and $NZ86 927 for non-preventable ADEs. ADEs and potential ADEs represent a considerable hazard for the pediatric inpatie...

Aims To identify drug usage/withdrawal in surgical patients and the relative risk this imposes on postoperative surgical complications. Methods A prospective survey of patients' medicines, oral intake (food/¯uids/ medicines) and postoperative complications was carried out in the General Surgical Unit, Dunedin Hospital, Dunedin, New Zealand. Results One thousand and twenty-®ve general surgical patients aged $ 16 years, were entered into the study. Half of the patients were taking medicines unrelated to surgery. On average these patients received 9 different drugs (range 1±47) from a selection of 251, of which 21% were released in the last 10 years. The mean number of these drugs taken increased with age, vascular surgery and other major procedures. The majority of patients (53%) were taking drugs for cardiovascular problems. Only 8% of admissions were on the drugs more traditionally recognized to be of importance to the surgery, i.e. steroids and diabetic therapy. With respect to risk, taking a drug unrelated to surgery was associated with an increased relative risk of a postoperative complication by 2.7 (95% C.I. 1.76±4.04) compared with those who were not taking any drug. Cardiovascular drugs contributed signi®cantly to this risk; when they were excluded from analysis, the risk dropped to 1.8 (95% C.I. 1.14±2.93). Death may be more common in those taking ACE inhibitors. Drug withdrawal and complications were analysed and as the time without medicines increased (range 1±42 days) so did the complication rate (x 2 =14.7, DF=2, P=0.007). Of those patients who were taking a cardiovascular medicine and were without their normal medicines for a period of time postoperatively, 12% suffered a cardiac complication. Conclusions Many patients admitted to a general surgical ward, are taking medicines unrelated to surgery. Drug therapy unrelated to surgery is a useful predictor for increased postoperative complications and one for which preventive action can be taken. This study provides evidence that withdrawal of regular medicines may add signi®cant risk to the surgery and further complicate outcome. The longer patients were without their regular medicines the more nonsurgical complications they suffered. Reintroduction of patients' regular medicines early in their postoperative course may decrease morbidity and mortality in-patients.

Patients exposed to a surgical safety checklist experience better postoperative outcomes, but this could simply reflect wider quality of care in hospitals where checklist use is routine.
