Assessment of dizziness among older patients at a family practice clinic: a chart audit study

BACKGROUND: Dizziness is a common complaint among the elderly with a prevalence of over 30% in people over the age of 65. Although it is a common problem the assessment and management of dizziness in the elderly is challenging for family physicians. There is little published research which assesses the quality of dizziness assessment and management by family physicians. METHODS: We conducted a retrospective, chart audit study of patients with dizziness attending the Sunnybrook Family Practice Center of Sunnybrook and Women's College Health Sciences Center (SWCHSC) in Toronto. We audited a random sample of 50 charts of patients from 310 eligible charts. Quality indicators across all dizziness subtypes were assessed. These quality indicators included: onset and course of symptoms; symptoms in patients' own words; number of medications used; postural blood pressure changes; symptoms of depression or anxiety; falls; syncope; diagnosis; outcome; specialty referrals. Quality indicators specific to each dizziness subtype were also audited. RESULTS: 310 charts satisfied inclusion criteria with 20 charts excluded and 50 charts were randomly generated. Documentation of key quality indicators in the management of dizziness was sub-optimal. Charts documenting patients' dizziness symptoms in their own words were more likely to have a clinical diagnosis compared to charts without (P = 0.002). CONCLUSIONS: Documentation of selected key quality indicators could be improved, especially that of patients' symptoms in their own words

Manobra de Epley repetida em uma mesma sessão na vertigem posicional paroxística benigna Epley’s maneuver in the same session in benign positional paroxysmal vertigo

OBJETIVO: Avaliar se a repetição de manobras de Epley em uma mesma sessão resulta em um menor número de sessões para abolir o nistagmo de posicionamento do que uma única manobra por sessão. MÉTODO: A manobra de Epley foi realizada em 123 pacientes com VPPB unilateral por ductolitíase do canal posterior. O grupo I foi composto por 75 pacientes submetidos a uma única manobra de Epley por sessão semanal e o grupo II foi constituído por 48 pacientes submetidos a quatro manobras na primeira sessão. RESULTADOS: O grupo II apresentou latência e duração do nistagmo maiores do que o grupo I (p<0,05). A média e o desvio-padrão do número de sessões apresentados pelo grupo I foram maiores do que no grupo II (p=0,008). Observou-se associação significante entre a distribuição do número de sessões e o grupo (p=0,039). O grupo II apresentou 21,4% a mais de pacientes que necessitaram apenas de uma sessão (IC 95% [7,7% - 35,1%]). CONCLUSÃO: A repetição de manobras de Epley em uma mesma sessão resulta em um menor número de sessões para abolir o nistagmo de posicionamento do que uma única manobra por sessão.<br>AIM: To assess whether more than one Epley’s maneuver in the same session, compared to a single one, decreases the number of sessions necessary to suppress positional nystagmus. METHOS: Epley’s maneuver was done in 123 patients with BPPV due to unilateral posterior semicircular canal canalolithiasis. The number of sessions for positional nystagmus suppression was compared in two groups of patients. Group I consisted of 75 patients submitted to a single Epley’s maneuver on weekly sessions and group II consisted of 48 patients that were submitted to four Epley’s maneuvers during the first session. RESULTS: Group II showed greater nystagmus latency and duration than group I (p<0.05). The number of sessions and standard deviation showed by group I was greater than in group II (p=0.008). We observed a significant association between number of sessions and group (p=0.039) studied. Group II had 21.4% more nystagmus-free patients following only one session (CI95% [7.7% - 35.1%]). CONCLUSION: Repeated Epley’s maneuvers in less sessions rendered more positional nystagmus-free patients when compared to those submitted to more sessions of single maneuvers
